CÉLESTE Mid-Weight Anti-Dust-Mite Duvet 350 g/m²

The curtains are closed, the bedroom is quiet, and all that remains is to slip under the duvet. When you settle down for the night, the right filling matters as much as the cover you have chosen. The CÉLESTE mid-weight cotton-shell duvet with an anti-dust-mite treatment brings a welcoming sense of loft to the bed and offers straightforward care for everyday use. It is a lovely addition to a room where you enjoy sleeping at a moderate temperature.

A 350 g/m² mid-weight duvet for temperate nights

With a 350 g/m² filling weight, CÉLESTE is a mid-weight or temperate duvet. It is worth considering when your bedroom is neither particularly hot nor especially cold. The range suggests a bedroom temperature of around 18–22°C as a general guide, although the season, your own warmth preferences and your other bedding make a difference too. Line quilting and white binding give the duvet its simple, tidy outline. Tucked into a plain or patterned duvet cover, it becomes a generous layer for a peaceful night’s rest.

A cotton shell and recycled filling fibres

The outer shell is 100% cotton, woven at 57 threads/cm². Inside, the filling is made from 100% polyester Lifill+Eco siliconised hollow fibres. Those filling fibres are made entirely from recycled material and GRS-certified (Global Recycled Standard). It is important to distinguish the two parts: cotton refers to the outer shell, while the GRS certification stated here concerns the recycled fibres in the filling. CÉLESTE is made in France. After washing or changing the bed, a gentle shake helps spread the filling evenly before you ease the duvet into the corners of its cover.

What does the anti-dust-mite treatment mean?

CÉLESTE has an anti-dust-mite treatment, a feature to consider if you are looking for bedding with this specific finish. That does not mean every dust mite is eliminated, and it does not guarantee that allergy symptoms will disappear. Keep up the usual habits that make your bedroom pleasant: ventilate the room, wash your duvet cover regularly and follow the care instructions for the duvet itself. If you are building a complete bedding set, you can pair CÉLESTE with the separately sold SIRIUS pillow, another item with an anti-dust-mite finish.

Four sizes to fit your bed and duvet cover

CÉLESTE comes in 140 × 200, 200 × 200, 240 × 220 and 260 × 240 cm. The smaller option is often used on a single bed, while the larger sizes suit different double beds and preferences for how much duvet hangs down at the sides. Before ordering, check the dimensions of your existing duvet cover and choose a duvet that matches. This avoids having empty corners or bunching the filling into one end. The width of your mattress, its height and whether you share the bed are also useful considerations. Explore the CÉLESTE collection if you want to discover more pieces from the range.

How to wash and care for the filling

The duvet can be machine washed at 30°C and tumble drying is permitted, following the instructions on the care label. Mamimosa’s tip: choose a machine with enough space for the duvet to move freely, rather than squeezing a large size tightly into the drum. After the cycle, gently shake it to help redistribute the filling and make sure it is completely dry before putting it back into its cover or storing it. This is especially important with larger sizes, because the centre can take longer to dry than the outer edges.

Frequently asked questions about CÉLESTE

Does the duvet come with a duvet cover?

No. You receive the filled duvet; its cover is a separate item and should be the same size.

Does the anti-dust-mite treatment replace regular washing?

No. The treatment does not replace normal bedding care or the recommended washing routine for the duvet.
